Area Forecast Discussion...UPDATED
National Weather Service Brownsville TX
107 AM CDT Sat Jul 25 2020

.DISCUSSION...Updated for latest aviation discussion below.

&&

.AVIATION...Currently, VFR conditions are prevailing across the
Rio Grande Valley, but aviation conditions will deteriorate
throughout the day on Saturday as Tropical Storm Hanna approaches
the Texas coast. This will lead to a very complicated and low
confidence forecast continues over the next 24 hours, with
amendments likely to the TAFs periodically. Showers and isolated
thunderstorms from the rain bands associated with Hanna should
start to impact the airfields early Saturday morning. By late
morning, winds will become very gusty, gusting between 35-45+
knots through Saturday night, with off/on heavy rain and
occasional rumbles of thunder. Wind directions will shift through
the period. Included low- level wind shear for all 3 TAF sites for
wind speeds/gusts between 40-60 knots at about 2000 feet above
ground level.

.PREV DISCUSSION... /issued 647 PM CDT Fri Jul 24 2020/

..00z Aviation Update...

DISCUSSION...Updated for latest aviation discussion below.

AVIATION...A very complicated and low confidence forecast over
the next 24 hours, with amendments likely to the TAFs periodically
as Tropical Storm Hanna approaches the lower Texas coast. The
main hazards in this TAF period are heavy rainfall, reducing
visibilities and ceilings, and very strong winds, including low-
level wind shear occurring over a few airports.

VFR conditions will prevail this evening, with light easterly
winds transitioning to southerly winds later this evening. Winds
will gradually turn westerly/northwesterly overnight tonight and
increase through the day on Saturday. By late morning,
west/northwest winds will become very gusty, gusting between
30-40+ knots through Saturday afternoon, with off/on heavy rain
and occasional rumbles of thunder. Included low-level wind shear
for MFE and HRL for wind speeds/gusts between 40-50 knots at 2000
feet above ground level. Although there is still lots of
uncertainty with timing and duration of the heavy rain/winds,
forecast confidence is very high that hazardous flying conditions
will occur starting overnight tonight and will continue to
deteriorate through the day tomorrow.

Overall forecast confidence: low

PREV DISCUSSION... /issued 440 PM CDT Fri Jul 24 2020/

.TROPICAL STORM HANNA THREATENS DEEP SOUTH TEXAS WITH DANGEROUS
FLOODING...

SHORT TERM (Now through Sunday Night): GOES-16 visible satellite
imagery continues to show better development of Tropical Storm Hanna
as it continues to move west-northwest across the northwest Gulf.
Deep convection continues to develop around its center. Latest
position from the NHC, as of 1 PM CDT, has the center of TS Hanna
located at 27.3N and 93.7W, moving west-northwest at 9 mph. KBRO
radar has been fairly quiet over land today, with most of the shower
and thunderstorm activity remaining offshore and on the immediate
coastline. Consistent runs of the HRRR have shown isolated to
scattered showers and thunderstorms developing across the CWA
later this afternoon and into this evening. Will continue to
monitor for heavy shower and thunderstorm development.

The NHC has the center of Hanna making landfall around Baffin Bay
either late Saturday afternoon or early Saturday evening, with it
turning more southwestward after landfall. Further strengthening of
TS Hanna is looking more and more likely at this point, with NHC
expecting a hurricane forming by the time it makes landfall. As of 4
PM CDT, Tropical Storm Warnings remain in effect across the lower
Texas coastal waters, all of Jim Hogg, Brooks, Kenedy, and Willacy
Counties, northern Hidalgo County, and coastal Cameron County.

The main impact with TS Hanna for deep South Texas continues to be
very heavy rainfall, which may produce life-threatening flash
flooding. Model guidance consensus has shifted the heaviest
precipitation slightly southward across the BRO CWA over the past 12
hours. The Weather Prediction Center (WPC) has included all of deep
South Texas in a Moderate Risk of FFG exceedance for D2 (Saturday)
and a Slight Risk of FFG exceedance for D3 (Sunday). Given all of
this and the possibility of Hanna further strengthening, went ahead
and increased QPF to reflect a general total rainfall accumulation
between 5 and 10 inches, with isolated amounts up to 15 inches,
across the CWA -- majority falling Saturday morning through early
Monday morning. A Flash Flood Watch remains in effect for all of
deep South Texas from 7 AM Saturday through 7 PM Sunday.

Another impact from TS Hanna will be tidal runup and minor coastal
flooding along the coast, with wave heights from swell and wind
waves building between 8 (nearshore) and 15 (offshore) feet. As a
result, surf conditions at local beaches of South Padre Island and
Boca Chica will become extremely rough and dangerous, with strong
rip currents, beginning this evening and continuing through the
majority of the weekend. A Coastal Flood Advisory remains in effect
from 4 AM Saturday until 7 PM CDT Sunday.

LONG TERM (Monday through Friday): As the remnants of Hanna
continue moving west over northern and central Mexico, broad
weakness in the 500 mb pattern will prevail over the TX coastline.
This in combination with the lingering tropical moisture over TX
and the western Gulf of Mex will maintain the threat of conv
throughout the first half of next week. After Wed, 500 mb ridging
will then build back east over the TX coastline which will start
shutting down the conv chcs over Deep South TX and the RGV during
the last half of the work week as the airmass dries out and
stabilizes. The cld cover and higher pops will likely hold down
the overall temps to near or a little below climo through Wed with
temps warming back up to above climo from Thurs through Sat.

MARINE (Now through Sun Night): Buoy 42020 reported north winds
around 14 knots, gusting to around 16 knots, with seas just above
4 feet with a period of 6 seconds at 1440 CDT/1940 UTC. Moderate
northerly winds and seas will persist through the rest of the
afternoon as Tropical Storm Hanna continues to progress westward
into the northwest Gulf of Mexico. Marine conditions will become
adverse beginning tonight with strong winds and increasing swell
as Hanna approaches the lower Texas coast, making landfall near
Baffin Bay early Saturday evening. Tropical storm force wind gusts
are likely, especially across the northern Gulf and bay waters
Saturday into Sunday morning. Tropical Storm Warnings remain in
effect for all of the lower Texas coastal waters, including the
Laguna Madre. Follow the latest updates on Tropical Storm Hanna
from the National Hurricane Center.

Mon through Wed: Surface ridging over the Gulf of Mex will
maintain a light to moderate onshore flow pattern along the lower
TX coastline next week with Bay condiions remaining below SCA
levels through midweek. The lower TX Gulf waters may see some
swells edging up into SCEC territory, but for now do not expect
any SCA conditions.
